No, you're just wrong. Hogg files don't work that way. There is no particular expectation that they will be the same for everyone. (I hesitate to explain how they really work, as I'm not sure how much of that information is public)
Surely all the people with different hogg files in this thread would have clued you in by now.
Check again. Others have confirmed same files are the same. If they have different ones they're corrupt. I've also tested this on three of my PCs, thank you very much. Not sure where you're getting your information from, but it's wrong. Unless you can link something? Yeah, didn't think so.
Compression for files is a lossless compression based on algorithms. It's not like lossy compression with JPEG image files which yield varying results if different PCs compress the files manually multiple times.
